The implication in your first sentence is that if the bedroom receivers were upgraded to HD then you could pause/rewind live TV on the remote DVR. This is not true. It can do it for recorded shows. Now if you meant the upgrade was to an HD DVR receiver, then this is also not true for the remote DVR. Of course, the local DVR can perform those functions.If you upgraded the receivers in bedrooms to HD, you'd be able to do that. But like I suggested before, you may need to add at least one more HD-DVR. Maybe one DVR could be used for sports and the other for family programming to help avoid issues where two HD receivers are trying to view the same DVR at the same time (which is not possible).
